Cliffhanger, much?
When I started reading, I was not aware that this book only covers the first week of the exchange mentioned in the blurb. So this story ends at a point where nothing is resolved. Meh. (I'm not a fan of cliffhangers, YMMV.)
Also, there's a LOT of drama for such a short amount of time covered in the book, and it took me a while to warm up to Mallory and the boys (not Mohammad, though, he was an insta-like :) ).
